its doesn't just pull it down, it perfectly copies the recoil patterns that can be found in the main post... tho there is still spread that is server sided so everything doesn't go into one spot (it does with weapon_accuracy_nospread 1)... so basically no pro can spray better than this
uh... press F4 and then you need to hold left mouse button to shoot, mby you changed the hotkeys in the file... did the older version work for you?
